Application filed February 21,-1927. Serial No. 169,760.

My invention relates to mechanical refrigeration, and particularly to means for increasing the heat'absorbing power of a refrigerant expansion unit, and the principal object of my invention is to produce a new and improved means of this type. In the drawings accompanying this specification and forming apart of this application I have shown, for purposes of illustration, various forms which my invention may assume, and in these drawings:

Figure 1 is a front elevation of one embodiment of my invention,

Figure 2 is a side elevation thereof,

Figures 3, 4, 5, are similar views showing other embodiments of my invention, while Figure 6 is a section on the line 6-6 of Figure 4.

The embodiment of my invention shown in Figures 1 and 2 comprises a plurality of containers 11 adaptedto receive brine or other heatconducting material, and having openings 12 for introducing such heat conducting material. Each of the containers 11 isco'nstructed with an aperture 13 extending entirely therethrough and of a size to fit closely over an expander drum 14 of a mechanical refrigeration system,- and with a second aperture 15 disposed laterally of the aperture 13 and adapted to receive and support ice trays.

In the embodiment of my invention disclosed in Figure 3 there is shown a sleevelike receptacle 16 passing through all of the apertures 15 of the containers 11, and in Figures 4: and 5 there is shown a shelf 17 dividing the apertures 18 of a pluralityof containers 19 into sections providing for supporting a plurality of ice trays 20 upon the containers 19 and the shelf 17. Figures 4:, 5, and 6 also show the containers 19 provided at their lateral edges, with laterally extending fins 21 which increase the heat conducting power of the containers 19. 1

From the above disclosure it will be obvious to those skilled in the art that I have provided new and improved means for increasing the heat absorbing power of a refrigerant expansion unit.

At the same time it will be obvious to those skilled in the art thatthe embodiment of my invention hereinshown and described may be variously changed and modified without departing from the spirit of my invention or sacrificing the advantages thereof, and it therefore will be understood that the disclosure herein is illustrative only, and that my inventibn is not limited thereto.

I claim:

1. In a mechanical refrigerating system, a cooling unit including a liquid refrigerant container, and a plurality of spaced parallel closed hollow brine receptacles surrounding said container, said receptacles having aligned apertures through which said container extends.

2. In a mechanical refrigerating system, a

cooling, unit including a liquid refrigerant container, and a plurality of separate-closed receptacles adapted'to contain brine, said receptacles having aligned openings therethrough Within their periphery through which said container extends.

3. In a mechanical refrigerating system, a cooling unit including a liquid refrigerant container, and a pluralityof separate closed brine receptacles through which said container extends and which are frictionally engaged thereby, said receptacles being formed.

with aligned openings remote from said container for the reception of a tray.

4:. In a mechanical refrigerating system, a cooling unit including a liquid refrigerant container, a plurality of closed brine contain ing receptacles, surrounding and frictionally engaging said container, said brine receptacles having aligned openings therethrough, and a tray receiving sleeve extending through the openings in said receptacles.

5. In a mechanical refrigerating system, a cooling unit including a liquid refrigerant container, a plurality of separate close-d brine signature. A

CHARLES G, SPREEN.
